The decentralized architecture of the Internet, which has been key to its development and worldwide deployment, is making it challenging to secure user experience with devices connected to the
Internet. In this talk, I will first give insights into the broad institutional ecosystem of public, private and international organizations contributing to cyber security drawn from a framework made using semi-supervised learning clustering on a database describing the institutions and their work on cyber security. In the second part, I will focus on the security and privacy of user’s voice records in speech recognition for command and control by studying encryption schemes to preserve user privacy, preventing the extraction of user specific information from voice records of voice-enabled devices.
